LOS ANGELES — It’s the 20th anniversary of RE+, the largest clean-energy show in North America that has returned to Anaheim.

The Horizon Hydrogen Grand Prix is happening at RE+ on Wednesday. Students from across the world created their own hydrogen-powered, remote-controlled cars that will undergo a six-hour endurance race.

Spectrum News went to Boyle Heights to meet the only all-girls group competing in the world championships.
